Description

Technical Field

[0001] This utility model relates to the field of urban drainage system technology, specifically to a water guiding system for vegetation greening in sponge cities. Background Technology

[0002] Like a sponge, a sponge city can absorb and drain rainwater during the rainy season, and the stored water resources can be reused.

[0003] CN 212689125 U discloses a water diversion system for vegetation greening in sponge cities, comprising a ground water trough with an outlet at its lower part. A filter device is connected to the lower part of the outlet, and a water storage device is connected to the lower part of the filter device. A recycling device is connected to the water storage device. This system aims to filter and adsorb impurities or toxic substances in rainwater to purify it, and stores the filtered rainwater in the water storage device for reuse. However, it has the following problems: 1. The drainage pipe layout is simple, which is not conducive to multi-directional vegetation irrigation; 2. As the filter layer thickness increases, the height of the filter device also increases, requiring deeper excavation and increasing construction difficulty. Utility Model Content

[0004] The purpose of this utility model is to provide a structurally reasonable and reliable water diversion system for sponge city vegetation greening that solves the above problems, facilitates multi-directional synchronous irrigation, is flexible and convenient to use, and has low construction difficulty and good filtration effect.

[0005] The technical solution of this utility model is:

[0006] A water guiding system for vegetation greening in sponge cities includes a water storage tank, a top cover, a filtration device, and water guiding components. The key technical features are: the filtration device is located at the center of the water storage tank and includes a first limiting cylinder, a second limiting cylinder, a third limiting cylinder, and a fourth limiting cylinder arranged concentrically from the inside out. The upper ends of the first and third limiting cylinders are fixed to the top cover, and their lower ends maintain a water passage distance from the bottom surface of the water storage tank. The lower ends of the second and fourth limiting cylinders are fixed to the bottom surface of the water storage tank, and their upper ends maintain a water passage distance from the top cover. The first limiting cylinder contains gravel filler, and a water guiding component is provided between the first and second limiting cylinders. The device includes pebble packing material, activated carbon packing material between the third and fourth limiting cylinders, an opening corresponding to the first limiting cylinder on the upper cover plate with a filter grid plate fixed thereon, and a water guiding assembly including a booster pump, an annular water supply pipeline connected to the booster pump, a water guiding riser, and a nozzle. The annular water supply pipeline is fixed to the inner edge of the upper cover plate. There are multiple water guiding risers evenly arranged above the upper cover plate. The lower end of each water guiding riser is connected to the annular water supply pipeline, and the upper end is connected to the nozzle via a retractable flexible pipeline. A retractable cylinder is hinged between the nozzle and the water guiding riser. The nozzles of each nozzle have different orientations.

[0007] In the aforementioned water guiding system for vegetation greening in sponge cities, two supports are symmetrically fixed on the outer wall of the fourth limiting cylinder. There are two lifting pumps, each fixed on one of the two supports. The lower end of the inlet pipe of the lifting pump extends toward the bottom of the water storage tank and maintains a set spacing. The outlet pipe of the lifting pump is connected to the annular water delivery pipe.

[0008] The aforementioned water guiding system for vegetation greening in sponge cities has a first right-angle connecting seat on the outer wall of the nozzle, a second right-angle connecting seat at the upper end of the water guiding riser, and the cylinder body of the telescopic cylinder is hinged to the second right-angle connecting seat, while the cylinder rod is hinged to the first right-angle connecting seat.

[0009] The above-mentioned water guiding system for vegetation greening in sponge cities has a first annular pressure plate on the upper edge of the second limiting cylinder that presses against cobblestone filler and activated carbon filler, and a second annular pressure plate on the upper edge of the fourth limiting cylinder that presses against activated carbon filler. The first and second annular pressure plates are respectively provided with groups of water passage holes.

[0010] In the aforementioned water diversion system for vegetation greening in sponge cities, the bottom surface of the water storage tank is an inclined surface.

[0011] The aforementioned water guiding system for vegetation greening in sponge cities has multiple hooks on the upper cover plate corresponding to the annular water delivery pipes.

[0012] The beneficial effects of this utility model are:

[0013] 1. The filter device filled with filter media includes a first limiting cylinder, a second limiting cylinder, a third limiting cylinder, and a fourth limiting cylinder arranged concentrically from the inside to the outside. Because it is arranged in the horizontal direction, compared with the existing technology, the excavation depth is shallow and the construction difficulty is small. Under the constraint of each limiting cylinder, the water flows downward through the crushed stone packing, then upward through the cobblestone packing, and finally through the activated carbon packing to complete the deflection, overflowing at the top edge of the fourth limiting cylinder, completing the entire filtration process. The filtration path is long and the filtration effect is good.

[0014] 2. The booster pump delivers the filtered water to the ring-shaped water supply pipeline, and then to the sprinklers through each water guide riser. This enables simultaneous irrigation in multiple directions. The pitch angle of the sprinklers can be adjusted using the telescopic cylinder, and each sprinkler has a different nozzle orientation, making it flexible and convenient to use.

[0018] The present invention will be described in detail with reference to the accompanying drawings.

[0019] like Figure 1 , Figure 2 As shown, the water guiding system for vegetation greening in sponge cities includes a water storage tank 12, an upper cover plate 6, a filter device, and water guiding components.

[0020] The filtration device is located at the center of the water storage tank 12 and includes a first limiting cylinder 22, a second limiting cylinder 19, a third limiting cylinder 17, and a fourth limiting cylinder 23 arranged concentrically from the inside out. The upper ends of the first limiting cylinder 22 and the third limiting cylinder 17 are fixed to the upper cover plate 6, and their lower ends maintain a water passage distance from the bottom surface of the water storage tank 12. The lower ends of the second limiting cylinder 19 and the fourth limiting cylinder 23 are fixed to the bottom surface of the water storage tank 12, and their upper ends maintain a water passage distance from the upper cover plate 6. The first limiting cylinder 22 contains crushed stone packing 21, the first limiting cylinder 22 and the second limiting cylinder 19 contain cobblestone packing 20, and the third limiting cylinder 17 and the fourth limiting cylinder 23 contain activated carbon packing 18. The upper cover plate 6 has an opening corresponding to the first limiting cylinder 22, and a filter grid plate 9 is fixed at the opening. In this embodiment, the upper edge of the second limiting cylinder 19 is provided with a first annular pressure plate 8 that presses against the cobblestone packing 20 and the activated carbon packing 18, and the upper edge of the fourth limiting cylinder 23 is provided with a second annular pressure plate 10 that presses against the activated carbon packing 18. The first annular pressure plate 8 and the second annular pressure plate 10 are respectively provided with a group of water passage holes.

[0021] The water guiding assembly includes a booster pump 14, an annular water supply pipe 7 connected to the booster pump 14, a water guiding riser 4, and a nozzle 1. The annular water supply pipe 7 is fixed to the inner surface edge of the upper cover plate 6. Multiple water guiding risers 4 are evenly arranged above the upper cover plate 6. The lower end of each water guiding riser 4 is connected to the annular water supply pipe 7, and the upper end is connected to the nozzle 1 via a retractable flexible pipe 3. A retractable cylinder 5 is hinged between the nozzle 1 and the water guiding riser 4, and the nozzles of each nozzle 1 have different orientations. In this embodiment, a first right-angle connecting seat 2 is provided on the outer wall of the nozzle 1, a second right-angle connecting seat 25 is provided at the upper end of the water guiding riser 4, the cylinder body of the retractable cylinder 5 is hinged to the second right-angle connecting seat 25, and the cylinder rod is hinged to the first right-angle connecting seat 2. Multiple hooks 11 corresponding to the annular water supply pipe 7 are provided on the upper cover plate 6.

[0022] In this embodiment, two supports 15 are symmetrically fixed on the outer wall of the fourth limiting cylinder 23. Two lifting pumps 14 are provided, each fixed to one of the two supports 15. The lower end of the inlet pipe 16 of the lifting pump 14 extends towards the bottom surface of the water storage tank 12 with a set spacing. The outlet pipe 13 of the lifting pump 14 is connected to the annular water delivery pipe 7. The bottom surface of the water storage tank 12 is an inclined surface 24.

[0023] Working principle:

[0024] During rainy weather, rainwater passes through the filter screen 9 and enters the first limiting cylinder 22. It then flows downwards through the crushed stone packing 21, upwards through the cobblestone packing 20, and finally through the activated carbon packing 18, completing the flow deflection. It overflows from the top of the fourth limiting cylinder 23, completing the filtration process. The first annular pressure plate 8 and the second annular pressure plate 10 do not obstruct the water flow but prevent the packing from shifting with the water flow. After filtration, the rainwater is stored in the water storage tank 12. Unfiltered impurities gradually settle at the lower position of the inclined surface 24 at the bottom of the water storage tank 12.

[0025] When water is needed for greening, two booster pumps 14 are started to transport the water in the storage tank 12 to the ring water supply pipeline 7, and then the water is transported by the ring water supply pipeline 7 to each water guide riser 4, and finally sprayed out by the nozzle 1. The pitch angle of the nozzle 1 can be adjusted by the telescopic cylinder 3. The nozzles of each nozzle 1 have different orientations, which is beneficial to the overall irrigation of the park.

[0026] The embodiments of this utility model have been described in detail above, but the content described is only a preferred embodiment of this utility model and should not be considered as limiting the scope of implementation of this utility model. All equivalent changes and improvements made within the scope of this utility model should still fall within the scope of this patent.
